Equivalent & Substitute Parts for SPB03B-15

Part Overview

The MEAN WELL USA Inc. SPB03B-15 is an isolated module DC-DC converter with a single output of 15V at 200mA, rated for 3W. It operates from an 18V to 36V input range, offers 1 kV isolation, and features Remote On/Off control, over-current protection (OCP), and short-circuit protection (SCP). The product is obsolete, requiring consideration of alternative models for design maintenance and available inventory.
